MODE 0F HANGING WINDOW-SASH.

Specification of Letters Patent No. 15,447, dated July 29', 1856.

To all whom it may concern:

Be it known that I, CROMWELL P. WEAVER, of the city of Philadelphia andState of Pennsylvania, have invented a new and Im proved Mode of HangingVindow-Sashes; and I do hereby declare the following is a full, clear,and eXact description of the same, reference being had to theaccompanying drawing and to the letters of reference marked thereon.

My invention consists in so connecting window sashes to bars arranged toslide in.

recesses in the j ambs of the window frame, that the said sashes may beremoved and replaced with facility. f

In order to enable others skilled in the art to make and use myinvention I will now proceed to describe its construction and operation.

On reference to the drawing which forms a part of this specificationFigure l, is an elevation (looking from the inside of a window frame,with sashes hung in my improved mode; Fig. 2, the same as Fig. l, withpart of the frame removed; Fig. 3, a side view in section on the line1-2 Fig. 2; Fig. 4, a transverse sectional plan, of part of the framethe sashes being both up; Fig. 5, a top view of part of the frame andsashes, with the lintel removed; Fig. 6, a perspective view of thesliding bar for one sash and Fig. 7 a perspective view of the slidingbar for the other sash. Figs. 4:, 5, 6, and 7 are drawn to an enlargedscale.

The same letters of reference allude to similar parts throughout theseveral views.

The frame of the window consists of the lintel A the two hollow j ambsB, B, and the sill C. The side pieces b and b of the jambs projectbeyond the cross piece c so as to form a recess for receiving thesliding bars D and E which together lit accurately, but so as to movefreely, therein.

On each of the sliding bars D is a projecting strip d one end of whichlits with a shoulder against the side b of the j amb, the other endforming a lip against which rests the side of the sash F. On the top ofeach of the sliding bars D is secured a light metal lip e which projectsa slight distance over the top of the sash F when the latter is in itsplace, it has also a metal strip f at the bottom, and on this rests thebottom of the sash.

Each of the sliding bars E has a projecting strip zagainst which bearsthe sash Gr it has also on the top a light metal lip i which projectsover the top of the said sash when the latter is in its place, and alsoa metal strip on which the sash rests.

On the bottom bar of the sash F (see Fig. 3) is a projection Z againstwhich bears the sash G, and the latter has a similar projection la atthetop bearing against the sash F. The bottom sash G has a spring latchm on each sidethe point of which ts an orifice in the flange of themetal strip j on thebottom of the sliding bar E from which the latchescan be withdrawn and replaced at pleasure. Each of the sliding bars Ehasa tongue n which fits in a groove in the cross piece e of the hollowj amb.

Each of the sliding bars D has a projecting bracket p to which one endof the cord R is connected., This cord passes upward and over a pulley Tthen downward and around the pulley SY then upward and over the pulleyI-I then downward ,again until it reaches a projection o on the slidingbar E to which projection the cord is attached. The pulleys H and T runloose on pins attached to a plate which is secured permanently to thecross-pieces c of the hollow jambs, and the pulley S is hung on a pin ina staple projecting from the counter-bal ance weight I.

The sliding bars D and E being placed in the recesses formed on theinside of the jambs, and the cords connected to the same as described,the two bars are first slid up to the top as seen in Fig. 3, the sash Fis then put into its place by inclining it so as to catch the metalstrips e e it is then easily pushed home so that the bottom of the sashrests on the strip f; the sash G is now connected to the sliding bars Fin a similar manner, and the points of the spring latches m allowed tocatch into the holes in the strip j.

ing bars, the latter With their sashes are al- D and E the same beingarranged and con- 10 Ways balanced at Whatever point they are structedsubstantially in the manner herein raised or lowered to. set forth forthe purpose of removing and I do Iot claim the emplofyment of asinglereplacing said sashes with facility. 5 Weight or t e balancing o sashes;but
